Isotachs

This is an image of isotachs on a map. Isotachs are a form of contour lines. This map shows the knots in Florida. Isotachs are used for weather purposes, mostly to measure wind.

Isobars

This is an image of Isobars. An isobar is a line of equal or constant pressure on a map. The lines are drawn to represent equal lines of pressure. Meteorologists use these types of maps when practicing the weather and climate conditions.

LIDAR

This is an image of Light Detection and Ranging (LIDAR). This LIDAR picture was taken above Kansas City. LIDAR shows an aerial view, that is also three dimensional. These types of images can be very helpful to tourist in an area.

Doppler radar


This is another one of my favorite types of images. I look for it everyday on the news. This is Doppler radar. Doppler radar mostly used to show thunderstorms and rain in ones area. It also shows where clouds are at, at a certain time. I like the Doppler radar because it shows how close rain is, and how sever the storms may be. Doppler radar is also a good estimate of how much time you have before a storm hits your area. This image shows that rain is close to the Fort Myers area, and the red indicates that the weather is very severe.

black and white aerial photo

Here is an image of a black and white aerial photo. Aerial photos are a picture of a land mass or certain area from far above, such as a helicopter, air plane, or sky scraper. This one shows a highway in Kansas City, the roads and intersections stand out because they show more of the "white." While the ground underneath the intersection is dark, and less noticeable because it shows more of the "black."

Infrared aerial photo


Infrared aerial photos are pictures of a product or land mass, the darker the colors, the more intense the area . In this case, this is an infrared aerial picture of a hurricane. The center of the hurricane (the eye) is red, and the dot in the very center is green, ...which means that these colors are the most intense area of the storm. There is also red in the outer layers of the hurricane, which shows that there are some intense storms beyond the center of the hurricane.

Cartographic Animations


This is seen all to much in Florida! What we see when a hurricane is coming on the local news is also called a cartographic animation. These type of maps are used specially for weather conditions and climate change.
